SHAVINGS FOR VINEGAR-GENEFATORS AND FOR CLARIFYING B EER.

, SPECIFICATION forming part of Letters Patent No. 437,902, datedOctober '7, 1890.

Application filed February 5, 1889.

To all whom it nmy concern:

Be it known that I, RUDOLPH I-I. I-IERDER, a citizen of the UnitedStates of America, residing at Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements inShavings for Vinegar-Generators and for Clarifying Beer, of which thefollowing is a specification, referencebeing had therein to theaccompanying drawings.

My invention relates to the wooden shavings principally employed in themanufacture of vinegar; and it consists in so shaping the obverse andreverse surfaces of the shaving that when packed in the vat or generatorthere shall be provided a series of connected ways or continuousconduits through which the liquid shall be free to pass and be exposedto the action of atmospheric air to aid acidification, which isaccelerated by bringing every portion of the fluid in contact with theair and thereby combining the wort with the oxygen thereof. I do not,however, limit the application of myinvention to the manufacture ofvinegar. It is equally servlcable for the clarification of beer inbreweries.

I denominate my improved chip by the generic term fluted shaving.

My invention is adapted to be packed within a generator injextendedstrips or coils, or both combined, all as hereinafter fully described,illustrated in the drawings, and specifically pointed out in the claims.

Referring to the accompanying drawings, wherein like letters ofreference point out similar parts on each figure, Figure l is a view ofa portion of a shaving constructed according to my invention. Fig. 2 isa view of the opposite side thereof. Fig. 3 represents shavings coiledup, parts being broken away.

The ordinary shaving is planed by special machinery, of dimensions aboutone foot in length and one-half inch wide thus forming a ribbon stripwhich coiled up becomes a close and compact volute, and when placed inthe generator will not subserve the purpose desired. These closely-woundcoils present no interstitial conduits for passage of air and wort, andtherefore, besides other objectionable features, offer an insufficientsurface.

Serial a. 298,777. (Specimens.)

My invention contemplates the provision of a wooden shaving that bypeculiar construction can be wound continuously from end to end uponitself into a volute, having, however, from edge to edge a series ofcontinuous spiral grooves or channels, thereby presenting the wholesurface of the wood to the action of the liquid.

In the drawings, A represents a fluted chip composed of a series ofintegrally-conjoined longitudinal sections of tubes a, the surfaces ofthese sections on one side being curved outwardly, as shown at a, whileupon the opposite side the tube-sections are curved inwardly, as shownat a The various fluted sections,being permanently conjoined, therebypresent at each point of juncture an angular projection or rib a Thesetubular sections extend the full length of each shaving, but preferablydiverge in a slightly-oblique direction, so that when the shaving iscoiled into a volute no portion of the curves will lie parallel with theplane of underlying or overlapping laminae. The curves a, a and ribs 0.will assume a given spiral pitch, leaving a diversity of irre ularsurfaces and variety of channels that will secure the most favorableresults for the purpose intended.

In forming the shavings I employ a peculiarly-shaped knife, whereby thefinished article is readily produced without further manipulation; but Ilay no claim herein to any special tool or machine for manufacturing theshaving.

Whether a fixed or revoluble generator is employed, there will beprovided by the use of my chips an indefinite number of channels andopenings permeating the whole mass. Some will be lateral and oblique,some spiral, and some sinuous-in fact, the direction of these openingsand channels will be varied and the liquid will pass over more of thewood surfaces than can be possible with any form of chip heretoforeprovided, the benefit of which has been hereinbefore pointed out.

What I claim, and desire to secure by Letters Patent of the UnitedStates of America,

1. A fluted shaving for employment in the manufacture of vinegar andbeer, having on one surface a series of invertedly-curved secposes,provided its full length with continu ous outwardly-extending curves onone side in an oblique direction, and invertedly-aligning curves on itsopposite surface coiled up into a volute, whereby a continuous spiralchannel will extend and surround the coiled shaving, as and for thepurpose intended, substantially as described In testimony whereof Iaffix mysignature in presence of two Witnesses.

RUDOLPH 1-1. HERDER.
